A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass. [2] Water-absorbing polymers, which are classified as hydrogels when mixed, [3] absorb aqueous solutions through hydrogen bonding with ...
Polyacrylic acid (PAA) and polyacrylamide are obtained by radical polymerization in water solution and used as thickeners, adhesives or flocculants. Acrylate and methacrylate homo- and copolymers are made by radical polymerization in toluene-acetone for coating applications.
A small amount of superabsorbent polymer material is taken (0.1g) and it is placed in the beaker. 100 ml of deionized water is poured into the beaker. After 20 min the swollen polymer was separated by using [filter paper] By weighing the polymer, one can find the swollen capacity of the SAP material. [3]
Devolatilization can be carried out when a polymer is in the solid or liquid phase, with the volatile components going into a liquid or gas phase. Examples are: Solid polymer, liquid phase: Extraction of caprolactam from polyamides with water. [4] Solid polymer, gas phase: Removal of ethylene from polyethylene via air or nitrogen in silos. [5]
Since polymer chains are often in close proximity to other parts of the same chain or to other chains, like-charged parts of the polymer repel each other. This repulsion leads to a swelling of the polymer. [citation needed] Polymers can also form micelles (spheres) in response to a change in pH. This behavior can occur with linear block copolymers.
Polymer solutions are solutions containing dissolved polymers. [1] These may be liquid solutions (e.g. in aqueous solution), or solid solutions (e.g. a substance which has been plasticized). [2] The introduction into the polymer of small amounts of a solvent (plasticizer) reduces the temperature of glass transition, the yield temperature, and ...
Aqueous biphasic systems (ABS) or aqueous two-phase systems (ATPS) are clean alternatives for traditional organic-water solvent extraction systems.. ABS are formed when either two polymers, one polymer and one kosmotropic salt, or two salts (one chaotropic salt and the other a kosmotropic salt) are mixed at appropriate concentrations or at a particular temperature.
Super-absorbent polymers (SAP) similar to sodium polyacrylate were developed in the 1960s by the U.S. Department of Agriculture. [3] Before the development of these substances, the best water absorbing materials were cellulosic or fiber-based like tissue paper, sponge, cotton, or fluff pulp.
